Sometimes, it is very hard to imagine the difference between sensor dimensions just by looking at specs. The picture here will give you a far better sense of the sensor sizes in the TG-820 iHS and ZS100.

All in all, each of these cameras enjoy different resolutions and different sensor dimensions. The TG-820 iHS because of its tinier sensor is going to make shooting bokeh trickier and the Panasonic ZS100 will give greater detail due to its extra 8 Megapixels. Greater resolution will help you crop photos far more aggressively. The more aged TG-820 iHS is going to be disadvantaged when it comes to sensor tech.
